Well I'm obviously new here, and joined so I could get advice and improve. I'm a senior in high school and I mostly shoot motorsports and cars. I have a Nikon D50 with just a Nikon 28-80mm that came with the camera when I bought it. I used to have a Nikon 55-200mm, but the AF motor went out randomly one day, so I'm in the market for a new lens or two.
